Mr. Saturns are a race of creatures resident to Saturn Valley, and speak in their own eccentric dialect, involving the use of verbal tics such as "Zoom", "Boing", "Ding", or "Dakota" at the end of most sentences, as well as a distinctive font from that used in the remainder of the games.
In EarthBound, they were captured by Master Belch, one of Giygas' henchmen. Once Master Belch is defeated by Ness and his party, the Mr. Saturn are freed and help Ness on his journey. They are shown to be surprisingly intelligent, as they assist Dr. Andonuts in making the Phase Distorter, allowing Ness to travel to the past and defeat Giygas. In Chapter 7 of Mother 3, the Mr. Saturn are captured and neutralized by the Pigmask Army with their Frightbots, with the goal of finding the location of one of the Seven Needles. Once freed by Lucas and his party, they reveal the location of the next Needle, found in Fire Mountain.
Mr. Saturn walks around the stage, pushing other items along with it. It also honks when making contact with an opponent. If thrown, it will deal very little damage and knockback, but it can be used repeatedly, as it does not disappear after one use. As an unconventional meteor smash, Mr. Saturn gives off a large amount of stun when it hits an opponent, making it great for combos. It also does a significant amount of shield damage—21 in Melee and 42 in Brawl. In Smash 4 and Ultimate, Mr. Saturn will always instantly break shields no matter how it is thrown, but can be perfect shielded as with other attacks.
Mr. Saturn can also be pulled out by using Vegetable, appearing with a chance of 1/300 in Melee, 1/128 in Brawl, and 1/116 in SSB4 and Ultimate.
In Brawl, the momentum of a projectile will affect the damage a character will receive; these are recorded in bounces.
In SSB4, damage varies based on distance. Projectiles thrown point-blank do more damage.
Note: A Mr. Saturn cannot be dropped while on the ground; the player will throw it instead.
